中小企业集群是一种有较强生命力的经济组织形式,但同时也较为普遍地出现了同质恶性竞争、成长速度慢等问题。本文提出通过内部外生型的企业成长模式来解决这一难题,这其中需要充分发挥第三方力量—尤其是行业协会的作用。影响行业协会发挥作用的关键因素是信任机制。比较而言,研究由信任关系缺失向构建“特殊性的不信任关系”转型更具有普遍意义。对于中小企业集群,“超级障碍”或“超级目标”的设置,将有助于这种转型的完成。根据信任基础的不同,可以选择试探型、联合型、深入型等不同的成长机制形式。 Small and medium-sized enterprise cluster is a form of economic organization with strong vitality, but at the same time it also has the problems of homogeneity and vicious competition, slow growth rate and so on. This paper proposes to solve this problem through the internal exogenous growth model, which needs to give full play to the power of third parties - especially the role of trade associations. The key factor influencing the role of industry associations is the trust mechanism. In comparison, it is more universal to study the transition from the lack of trust relationship to the construction of the “special no-trust relationship.” For SME clusters, the setting of “super hurdles” or “super goals” will help shape this transition. Depending on the basis of trust, you can choose to explore, joint, in-depth and other forms of growth mechanism.
